Hi,
I'm using PMS on Synology DS916+ (2GB RAM). I have 4K video for testing purposes. Video has pgs subtitles embedded. I've added external SRT subtitle. Client app is on Samsung 2016 UHD TV. Connection is wired. When I play video, no matter Direct Play or Direct Stream, WITH ANY of subtitles included (pgs or srt), I have heavy transcoding on Synology side and hude lag/stuttering/breakdown on client side. No matter what I'm turning on or of on server side. I've tired 'Burn subtitles' settings all of three, Direct Play +/- Direct Stream,...Any combination that includes subtitles triggers transcoding on PMS side and produces huge lad and eventually breaks down.
On the other hand, when I play same file with setting on client side: Subtitles = NONE, it plays 4K file smoothly that I can even use fast forward and it responds immediately.
I don't need to mention that subtitle naming rule is in place, PMS detects sub as External, etc...
PMS version for Synology: 1.1.4.2757-24ffd60
Samsung TV clients app version: 3.0.4 (2.10.0)
Tizen: 2.4
Any suggestions that doesn't include free format conversion software and any video conversion at all?
Thanks.
